If you are a mainly a desktop consumer: block them using /etc/hosts

On Windows, it is at C:\Windows\Windows32\drivers\etc\hosts

In the hosts file, you put `0.0.0.0 <site you don't want to visit>`. Now whenever you go to that site, it just doesn't exist and if you _have_ to open it, you need to go comment out the line in the hosts file.

It's frequently enough friction but you have to remember to uncomment the line after you are done.

You can do the same for mobile but it involves setting up a VPN. That is how the paid apps that do the same work.

Also at the end of each day, do a reflection and ask yourself "What would I have done differently today?" or some variation. That frequently gives a stopgap where I resolve myself to do things different the next day.

It sucks to lose a few hours, it really sucks to lose a few days just because you fell into a rut.
